The form below allows you to enter (B-V)o values and convert them to Log Teff and plain old Teff values. I'll bet you're really thrilled about this aren't you?

For Main Sequence, and Giants (III, IV, V, VI)

(B-V)o Value
Log Temperature =
Temperature =
Bolometric Correction =

For Supergiants (I, II)

(B-V)o Value
Log Temperature =
Temperature =
Bolometric Correction =
